SECTION 9105/911
6. SYSTEM ENVIRONMENTAL AND INSTALLATION REQUIREMENTS
Class of Service
5.02 The station features can, for convenience. be grouped into sets
of different Classes of Service (up to a maximum of 16). Each
Class of Service incorporates a different combination of features and
restrictions allocated to that Class of Service.
5.03 Section
fully describes the system programming which allows the fea-
tures to be properly coordinated with the system requirements for the
trunks, extension lines and Attendant Console. The customer's particu-
lar requirements are met by entering the appropriate data from the
Attendant (or Maintenance) Console; the Class-of-Service Option be-
ing one example of such data.
General
6.01 This Part is concerned with the design parameters of the PBX
system insofar as they are affected by environmental con-
ditions. Electrical characteristics and performance are detailed in the
subsequent parts of this Section.
6.02 The parameters in this Part are segregated into the following
subparts: Design Data and Compatibility as detailed in para-
graphs 6.03 and 6.04, Shipping and Storage data as detailed in para-
graph 6.05 and Installation Requirements as detailed in paragraphs 6.06
to 6.09.
Design Data
6.03
The PBX systems are designed to operate within the following
environmental conditions:
Temperature. The systems operate satisfactorily in the range of
0°C to 40°C (32°F to 104°F) maximum. These are ambient tem-
peratures as measured at a point 150.1 cm (59.1 in.) above the
floor and 3.81 cm (1.5 in.) in front of the equipment.
Relative Humidity Range. The system operates when subjected
to a relative humidity range of 10 % to 90 %, noncondensing.
Acoustic Noise. The systems do not radiate acoustic noise
greater than 45 dB SPL, "A" weighted, measured 1200 mm (47.2
in.) from the center of the cabinet.
Vibration. The systems operate satisfactorily when subjected to
a continuous vibration of 5-200 Hz with an acceleration of 0.5
Electrostatic Discharge. The systems meet the following elec-
trostatic discharge test:
